HOBBY?!

from 'four things every musician's gotta know' #1: Hobby vs. Service. A hobby is noncommercial. You can start and stop whenever you want, you don't have to work continuously to hone it, spend time and money advertising it, or carry equipment. However, when the time, place, duration, and high quality are all specified, that's not a hobby any more-- It's a service, especially in a business BASED on (making money from) that service.
